Pontiac Trans Sport (EU)

Coolant capacity & service interval

Pontiac Trans Sport (EU) coolant capacity ranges from 11,05 to 12,75 liters. Service intervals require changes every 60000 km or 48 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Trans Sport 3.8 V6 (1991-1995)
  • Use: Normal
  • Capacity 11,05 liter
  • Change 60000 km/ 48 months

Additional Notes

  • The Pontiac Trans Sport (EU) coolant system spans two engine configurations: a 2.3-liter four-cylinder covering 1992-1996 and a 3.8 V6 covering 1991-1995.
  • Both the 2.3 and the 3.8 V6 share a base cooling system capacity of 11.05 liters, indicating a closely matched system volume despite the difference in engine displacement.
  • The 2.3 variant carries an additional capacity figure of 12.75 liters when the vehicle is equipped with rear air conditioning, reflecting the extra coolant volume required to serve the rear climate circuit.
  • The 1.70-liter difference between the standard and rear air conditioning capacity on the 2.3 represents a meaningful fill distinction, and using the wrong figure during a service fill could result in an underfilled or overfilled system.
  • The 3.8 V6 lists only a single capacity value of 11.05 liters with no rear air conditioning variant, meaning no alternative fill volume applies to that engine configuration.
  • Both configurations share an identical service interval of 60,000 km or 48 months under normal use conditions, whichever comes first, placing coolant renewal on a combined distance-and-time schedule rather than distance alone.
